Abstract: A composite molded wheel assembly and method of construction wherein a separately formed injection molded tread is flow melt bonded to a blow molded rim. The tread may comprise multiple tread pieces which are spaced over a tread surface. Bond enhancing grooves and/or projections may be provided on inner surfaces of the tread pieces and/or rim. The tread pieces flow melt bond to the rim during the molding of the rim. The rim includes an axle bore containing hub, a tread support wheel box and a plurality of connecting spokes and intervening web pieces. The method includes the steps of preparing and retaining the tread within the rim forming mold, introducing a parison of rim material having a melt temperature greater than the tread material, injecting pressurized air or gas to conform the rim material to the mold and tread pieces and controlling the molding cycle temperature, pressure and time parameters to promote bonding.

Abstract: A twist free fish stringer having a removeable end stop. A flexible length of cording includes a crimp coupled threading needle, a crimp coupled swivel assembly and one or more bored stop sleeves. A flanged end stop includes a spacer portion and through bore and is slidably retained along the cord to a selected stop sleeve via a hairpin clip which is tethered to the end stop. Alternative end stops and belt or wader mounted stringer retainers are also disclosed.
Abstract: A slide track, pin registration system for registering photosensitive media to light exposure equipment. The system includes one or more slide tracks and each of which contain media registration pins. The slide tracks are orthogonally mounted within grooves let into a resilient media support mat. Each pin is restrained in a spring biased retainer which retainer is loosely confined in a support base that slide mounts to the track. The number of pins and profile shapes are variable to match the media and registration requirements. In one vacuum system, the tracks are supported in a multi-chambered, foam backed bladder. In another the tracks are supported on a single chambered bladder. In still another system, the retainer slides within grooves formed in a rigid board.

Abstract: A hinged gambrel support which folds and latches for storage. Each of a pair of support arms include one or more gambrel retainer projections, mating latch surfaces and tie off apertures. A bored axle at one arm mates with and is retained to the other arm at a recessed bore via a split ring fastener. Latch surfaces at the retainer projections interlock upon folding the arms for storage. In an alternative construction the arms are length adjustable.
Abstract: Liquid containment apparatus comprising a metal storage tank mounted within a liquid impermeable, cast concrete vault. An open-topped, reinforced cast concrete vault base includes an internal thermal liner, liquid impermeable membrane, vault seal, tank cradles and support legs. Sloped interior walls, a sump and siphon facilitate liquid and/or condensate removal from the base. A vault cover is integrally cast with the tank and supports a number of projecting fill, vent, gauge, inspection, and siphon standpipes. Chamfered edges at the cover and lift hooks facilitate cover removal, alignment and tank inspection.
Abstract: A wind powered vehicle including an operator platform having tilting and stationary sections coupled together via a plurality of hanger bearings and a longitudinal pivot axle. The platform section tilts with foot pressure applied at a stirrup to direct a forward steering assembly. The stationary platform section includes a resilient suspension and supports an opposite foot of the operator. The forward steering assembly provides a tilting, center biased steering turntable and axle. Adjustable axle bearing collar support and shock absorbers support forward and aft pairs of skis, wheels or runners which are tilted at opposite caster angles. The steering assembly, hanger bearings, cable truss supports and a sail coupler are each longitudinally adjustable along the length of the platform. In alternative configurations, wheels are mounted to the fore and aft axles; the platform includes spray guards; or the vehicle is constructed with water skis and the platform is constructed to provide flotation.
Abstract: Low volume, personal water purification systems including cartridges containing multi-valent iodine resins, granulated active carbons, and porous separation and filtration means. In one assembly, a first section of a multi-sectioned cartridge includes an inlet, a mouthpiece and a coupler. A second section includes mating coupling means and each section includes separate filtration and/or purification media. In other assemblies, cartridges of a variety of filtration/purification organizations mount within squeezable, vented housings including straws or self-sealing outlet ports. In still other assemblies, the cartridges couple to a manifold housing.

Abstract: A micro-component feeder assembly supporting small, odd lot or odd shaped components and subassemblies from a sprocket driven tape carrier including seriatim, annular housings having removable covers and component pallets. The housing walls include resiliently fastener portions which resiliently support each pallet and cover. One or more components are indexed to pallet apertures, cavities, projections or resilient restraints.Wound tape supply and take-up cartridges mount to a controlled drive housing which includes tape reel drive, tape splice, tape sprocket drive, cover removal, clamp/test and lift and locate assemblies. Full and depleted component tapes cyclically alternate between upper and lower cartridges.A multi-faceted tool head assembly is controlled to a defined pallet presentation and defined positions at each pallet. A component gripper assembly produces a uniform gripping and insertion action of each component.
Abstract: A piezoelectric resilient arm contacts a projected object and establishes a reference relative to sensitivity means and differential detector means including feedback coupled amplifier means which operates in cooperation with a balanced square wave generator means for producing a switched output upon detecting motion. An alarm signal is produced which has a duration related to the rate of change of movement of the piezoelectric resilient arm. Programmable delay means appropriately enables an annunciator and/or wireless communication link to a system controller.
Abstract: A braking system for in-line skates including a spring biased, pivotally mounted skid pad and wheel pad. The system includes a bracket which mounted to a wheel track and to which a pad support arm is pivotally mounted. A flanged skid pad and flanged wheel pad mount to mating channels of the support arm. A leaf spring provides a controlled bias to the pad support arm, skid pad and wheel pad and provides a controlled stopping action without skidding.
Abstract: An internally mounted, collapsible tent support framework including a plurality of length adjustable support sections. Inverted V-shaped end supports slip couple to a telescoping ridge pole assembly which includes a telescoping vertical T-support and over which a fabric tent is suspended. Set screws fasteners at the ridge and T-support assemblies determine exposure length and support camp accessories. Slip couplers including coaxial inner and outer sleeves define annular coupling cavities at the end supports.
Abstract: An imaging support assembly for precise and repeatable alignment and registration of plural, planar workpieces having a plurality of projecting registration pin assemblies. The workpieces contain holes where projecting pins of the registration pin assemblies are received. At least one of the registration pin assemblies contains a projecting pin of a non-circular shape when viewed end-on. A flanged barrel of the assembly is rigidly mounted to a planar support board. The projecting pin is spring biased within a sleeve that mounts in the barrel. The pin projects through a barrel aperture and is non-rotatively movable in the plane of the board within limits defined by the barrel aperture.
Abstract: Durable, colorfast elastomer fishing lure dressings and lures including same wherein silicone based colorants are printed onto the dressing material. In a preferred construction, a planar, elastomer substrate is printed on desired upper and lower surfaces with a silicone based colorant in desired patterns. The colorant is permanently fixed in a subsequent thermal curing step. Metalized, accent foils may be bonded to the colorant before curing. The colorant comprises a liquid vinyl silicone carrier which may include varieties of colored pigments, scents, glitters and chromatic particulates.
